GUY MORGAN LAIRD, OF HILLSBORO, ILLINOIS.

ATTACHMENT FOR ELECTRIC LAMPS.

Specification of Letters Patent.

Application filed February 8, 1915. Serial No. 6,828.

T 0 all whom it may concern:

Be it known that I, GUY M. LAIRD, a citizen of the United States, residing at Hillsboro, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Attachments for Electric Lamps, of which the'following is a specification, reference being had to the accompanying drawings.

My invention relates to attachments whereby an electric lamp may be mounted upon a dry battery, and the primary object of my invention is the provision of a very simple device of this character which may be'readily mounted upon any dry battery and connected up therewith, and in which the circuit through the battery is normally broken, but may be completed either intermittently or continuously for any desired length of time.

A further object of the invention is to form the attachment of practically one continuous strip of metal bent so as to embrace the battery and clamp upon it to form a handle and form a circuit closer.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a top plan view of the attachment, thehandle being broken away; Fig. 2 is a side elevation of the attachment applied, the battery being shown in dotted lines and part of the clamping member of the attachment being in-section; Fig. 3 is a detail sectional view on the line 33 of Fig. 1; Fig. 4 is a detail view showing a portion of the arm and the hook on the circuit closer.

Referring to these figures, it will be seen that my attachment is formed of a single strip of metal 2, having uniform width, and in actual practice about twenty-one inches long. One end of the strip 2 is outwardly bent as at 3 and is then bent into a circle so as to surround and clamp upon a dry cell. At a point 4 the material of the strip is outwardly bent and then rebent upon itself to form an outwardly projecting abutment or flange 5 confronting the flange 3 and adapted to be engaged with and drawn toward said flange, to thereby contract the battery clamping ring by means of a bolt 6. After being rebent upon itself as at 5 the bend is "continued toward the other end of the strip as at 7 shown in Fig. 3, and is then folded on a. line at forty-five degrees to its edge and extended upward as at 8. The strip is extended upward and then diametrically across the circular band 2 or ring to form a handle 9 which at its forward end is curved downwardly and inwardly as at 10, then extends straight downward as at 11 and is bent outward as at 12 and then extends downward again as at 13. The strip is then rebent upon itself as at 14 and then extended radially inward as at 15 and extended upward as at 16, then outward and upward as at 17, and then is formed with an ear 18 cut so as to provide a hook 19 adapted to engage with the forward curved extremity of the handle 9.

The portion 15 of the strip is perforated to engage with a binding screw 20 on the dry Patented Apr. 4, 1916. I

battery 21. Mounted upon the portion 16 of the strip is a U-shaped member 22 which is insulated from the strip by means of the insulating plates 23, as shown clearly in Fig. 1. A- conductor 2 1 is connected to this U-shaped member 22, the other end of the conductor being adapted to be engaged by the binding screw 23 on one pole of the battery. The purpose of bending the strip as at 10 and 12 is to provide a seat for a lamp housing and reflector, designated 25. Thi strip also carries upon it a metallic socket '26 which is threaded for the reception of the usual electric'light plug, the outer end of which is designated 27. and is lllllStl'HlIGd. in Fig. 2. The socket 26 is electrically connected to one pole of the battery by means of the portions 12, 13, 14 and 15 of the strip, while the contact member on the plug is adapted to be electrically connected to the other pole of the battery by forcing the circuit closing portion of the strip outward so as to bring the member 22 in electrical engagement with the extremity of the plug. The portion 15, 16 and 17, in other words, the resilient arm extending upward from the strip which forms the handle at a point beyond'the engagement ofthe strip with the binding screw 20, forms a circuit breaker or a circuit closer. As illustrated, this strip 15, 16 and 17 is formed integral with or in one piece withthe strip which forms the handle and therefore the contact member 22, which n is insulated in any suitable manner from the remainder of the attachment and therefore acts as the contact itself. Normally the resilience of the portions 15, 16 and 17 of the strip forming the circuit closer will hold the contact member 22 away from the plug, but

when the circuit closing portion'of the strip is forced forward by the action of the thumb on the portion 17 of the strip the circuit will be closed'and the lamp will be energized. If the circuit closer 17 of the strip be forced forward and then the hook 19 engaged with the handle, the contact member 22 will be held in electrical engagement with the plug and the lamp will continue to burn until the hook 19 is disengaged from the handle. It will thus be seen that this device may be used either as a flash lamp or as a steadily burning lamp.

It will be obvious that this device can be quickly attached to any standard dry battery cell. by the thumb or by a finger of the hand and the light can either be flashed or made continuous.

member 22, is made from only one strip of sheet metal. This metal is not riveted and is formed with only four holes punched in it, ,two for the screw, one for the reflector and base socket, and one for the screw 20.
